Answer:
right angle triangle
Step-by-step explanation:
2x+3x-10+110-x
4x/4x =80/4x
x=20°
A=40°
B=50°
C=90°
4× 4 3/10= 4×43/10= 86/5= 17 1/5
Answer: f(3)= 7, f(0)= -5, f(-2)= -13
Step-by-step explanation:
Substitute and plug in.
For f(3), we plug in 3 for x in the equation.
So, 4(3)-5, which is just 12-5, which is 7
We do the same for f(0),
4(0)-5, which is 0-5, which is -5
Once again for f(-2),
4(-2)-5, which is -8-5, which is -13
Hope this helps!
